    Dynamical Evidence for a Black Hole in GX 339-4
    We present outburst spectroscopy of GX 339-4 that may reveal the motion of its elusive companion star. N III lines exhibit sharp emission components moving over...

    Dynamical Masses of the Binary Brown Dwarf GJ 569 Bab
    We have obtained new images and high-resolution (R~22,400) near-infrared (1.2400-1.2575 μm) spectra of each component of the brown dwarf binary GJ 569 Bab using...

    Dynamical Structure of Small Bulges Reveals Their Early Formation in ΛCDM Paradigm
    The Λ cold dark matter (ΛCDM) paradigm of galaxy formation predicts that dense spheroidal stellar structures invariably grow at early cosmic time. These...

    Dynamics of Multi-cored Magnetic Structures in the Quiet Sun
    We report on the dynamical interaction of quiet-Sun magnetic fields and granular convection in the solar photosphere as seen by Sunrise. We use high spatial...

    Early Coformation of the Milky Way's Thin and Thick Disks at Redshift z > 2
    The Milky Way serves as a template for understanding the formation and evolution of late-type massive disk galaxies since we can obtain detailed chemical and...

    Early-type Galaxies with Tidal Debris and Their Scaling Relations in the Spitzer Survey of Stellar Structure in Galaxies (S4G)
    Tidal debris around galaxies can yield important clues on their evolution. We have identified tidal debris in 11 early-type galaxies (T

    Effects of Spectral Resolution on Simple Magnetic Field Diagnostics of the Mg II H and K Lines
    We study the effects of finite spectral resolution on the magnetic field values retrieved through the weak-field approximation (WFA) from the cores of the Mg II...

    Electric Dipole Emission by Fulleranes and Galactic Anomalous Microwave Emission
    We study the rotation rates and electric dipole emission of hydrogenated icosahedral fullerenes (single and multishell) in various phases of the interstellar...

    Elusive Magnetic Structures in the Sun and Solar-Type Stars
    The magnetic structures of the Sun are very inhomogeneous, with irregularities smaller than the smallest sizes that we resolve from Earth. Such irregularities...
